Detailed Product Description
Radio Remote Controls have become a key element within a modern working context where safety, productivity, freedom of movement has a continuously increasing importance. Industrial radio controllers are consequently for time saving and risk reduction working instruments.
Thanks to the radio controller, the operator stands in the place with the best visibility and lowest operation risk. The wireless technology allows controlling the machine in full autonomy without requiring other operators to support the job with indications.

You will be certain that no other radio device will take over the control of your application thanks to an exclusive communication channel protected by a unique ID code that IMET assigns to each radio remote control.

This device operates in continuous transmission between the transmitting and receiving units. The radio link is made of digital communication frames that are monitored by algorithms at the reception. This guarantee an absolute correspondence between the commands sent by the operator and the received commands. When the radio link is too disturbed or interrupted the receiver unit will autonomously turn into Stop mode bringing the machine to a safe status.

Our Radio controllers are based on designing and manufacturing concepts aiming to guarantee safety and reliability. For example, the CPU features dual microprocessors in cross checking, STOP circuit is made of monitored double safety relays, S-STOP relay is available for the reduction of motion command failure risk, error and failure test are performed at each transmitter and receiver powering.
